Arianna gathered data about the distance of 20 cities from the equator and the average hours of sunlight per day in December for
stich3 [128]

<u>Answer-</u>

<em>A. strong negative correlation.</em>

<u>Solution-</u>

<u>Direction of a relationship</u>

  1. Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
  2. Negative- If one variable increases, the other tends to decrease, and vice-versa.  It is represented by negative numbers(i.e 0 to -1)

<u>Strength of a relationship</u>

  1. Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
  2. No relationship- When two variables have no relationship at all, their correlation is 0.

As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.

What’s the length of three pipes, when combined they equal 72m, how do I find the answer
allochka39001 [22]

Answer:

Each pipe is 24m

Step-by-step explanation:

<u>Given:</u>

  • three pipes
  • combined equal 72m
  • let the variable x represent the length of 1 pipe

<u>Algebraic Expression</u>:

3 pipes times length equals 72m (the total length)

3x = 72, we want x to be alone so divided both sides by 3

3x / 3 = 72 / 3

x = 24
